OBJECTIVE
The purpose of this study was to determine the efficacy of sonography for revealing osteochondritis dissecans of the humeral capitellum.
SUBJECTS AND METHODS
Twenty-seven patients with capitellar osteochondritis dissecans (27 males; range, 11-20 years; mean age, 14 years) underwent radiography and sonography performed with a 7.5-MHz mechanical sector probe. Lesions were assessed as stable or unstable. The sonographic assessment was compared with radiographic assessment in 27 patients, MR assessment obtained in 10, and surgical findings in 15.
RESULTS
Sonographic assessment agreed with radiographic assessment in 23 of the 27 patients, MR assessment in nine of the 10, and surgical findings in 14 of the 15. Sonography revealed that two lesions, which had been underestimated on radiography, were unstable.
CONCLUSION
Sonography facilitates the assessment of capitellar lesions so that treatment can be optimized.
目的
本研究旨在确定超声检查对揭示肱骨小头剥脱性骨软骨炎的有效性。
研究对象与方法
27例肱骨小头剥脱性骨软骨炎患者（均为男性；年龄范围11 - 20岁；平均年龄14岁）接受了X线摄影及使用7.5MHz机械扇形探头进行的超声检查。病变被评估为稳定或不稳定。对27例患者的超声评估结果与X线摄影评估结果、10例患者的磁共振成像（MR）评估结果以及15例患者的手术结果进行了比较。
结果
27例患者中，超声评估与X线摄影评估结果相符的有23例，与10例患者的MR评估结果相符的有9例，与15例患者的手术结果相符的有14例。超声检查发现，X线摄影低估的2处病变为不稳定病变。
结论
超声检查有助于评估肱骨小头病变，从而优化治疗方案。
